The present invention relates to new and useful improvements in toolsparticularly for automobile repair shops but it is to be understood, ofcourse, that a device in accordance with the presout invention may beused for any purpose for which it may be found adapted and desirable.

The primary object of the invention is to provide, in a manner ashereinafter set forth, a tool of the aforementioned character embodyinga novel construction, combination and arrangement of parts through themedium of which king pins, bushings, bearings, spring perches, etc., maybe expeditiously removed and replaced with a minimum of effort.

Another very important object of the invention is to provide a tool ofthe character described embodying a construction which is such that asubstantially conventional hydraulic or mechanical jack, particularlythe former, may be used as the go source of power.

Other objects of the invention are to provide a tool of the characterset forth which will be comparatively simple in construction, strong,durable, highly efficient and reliable in use, compact, light in weightand which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the following specifica-0 tion, taken in connection with the accompanying drawings wherein likecharacters of reference designate corresponding parts throughout theseveral views, and wherein:

Figure 13 is a view in horizontal section, taken substantially on theline |3-|3 of Fig. 12.

Figure 14 is a view in elevation of the rod which 16 is used forremoving shackle pins or bolts.

Referring now to the drawings in detail, it will be seen that thereference numeral I designates a substantially fiat, rectangular base ofsuitable material, preferably metal, having formed there- 20 in aplurality of slots 2. Threaded for adjustment in the lower side of thebase I is a plurality of supporting legs 3. The reference numeral 4designates a hydraulic jack which is mounted on the base I, said jackcomprising a slidable tubux other end portions of the arms 6 extendthrough the slots 2 and are adjustably anchored therein through themedium of cross pins 8.

A metallic member 9 is provided which is adapted to rest on or againstthe work and which is provided with inwardly inclined marginal portionsID with which the hooks l are engageable, as illustrated to advantage inFig. l of the drawings. The member 9 is further provided with an,opening H for the passage of the king pin as it is removed.

A metallic rod I2 is provided for actuation by the jack 4. The rod 12includes an enlarged end portion l3 which is adapted to be inserted inthe upper end portion of the tubular piston 5 of the jack 4, togetherwith a flange I4 which rests on the upper end of said tubular piston 5.At its other end, the rod 12 is reduced, as at [5, this end of said rodbeing engageable with the king pm.

In Figure 1 of the drawings, the reference numeral l6 designates aspindle assembly on one end of the front axle ll of an automobile. Theking pin which connects the spindle assembly IE to the axle I1 isindicated at l8. It is thought that the manner of using the device forremoving king pins will now be readily apparent. The base I and the jack4 are positioned beneath the work, the rod I2 is mounted in the jackpiston 5, the member 9 is mounted on top of the spindle assembly 5 in amanner to encircle the head of the king pin, after which the hooks I ofthe arms 6 are engaged with said member 9. The jack 4 is now actuated toraise the rod l2, thus forcing the king pin it out of the spindleassembly l6 and the axle H.

To meet various conditions, such as those encountered on difierent makesand models of automobiles, a substantially rectangular metallic memberl9 (see Fig. 7) is provided for use in lieu of the member 9. Thesubstantially rectangular member l9 comprises inwardly inclined marginalportions 20 for" engagement by the hooks I.

In Fig. 6 of the drawings, there is shown a hook engaging member whichis particularly adapted for use in removing spring perches on the frontaxles of certain types of automobiles, particularly the Ford. Thismember is designated generally by the reference numeral 21! andcomprises a substantially U-shaped element 22 the legs 23 of which areadapted to straddle the usual radius rod of the automobile. Slidablymounted on the legs 23 is a removable block 24. The legs 23 are providedwith inwardly inclined upper surfaces 25 for engagement by the hooks 1.

When the member 2| is used, the closed end portion of the U-shapedelement22 rests on the axle I1 and the legs 23 straddle the spring perchto be removed and the adjacent end portion of the radius rod. The block24 is then slipped on the legs 23 and rests on the radius rod afterwhich the hooks I may be engaged with said legs 23. The operation forremoving the spring perch is now substantially similar to thathereinbefore described for removing a king pin.

In Figs. 9 to 13, inclusive, of the drawings, there is shown anarrangement which is particularly adapted for removing and insertingbushings, such as those for the king pins of an automobile. When thisbushing removing and inserting means is in use it will be understoodthat the spindle assembly has been removed from the axle. The referencenumeral 26 designates a metallic plate member which is engageable withthe spindle assembly and which has formed therein slots 27 whichaccommodate the hooked end portions of the arms 6 for permitting thehooks I to be engaged with said plate. The reference numeral 28designates a rod having a reduced end portion 29 which is adapted to beinserted in the tubular jack piston 5, said reduced portion 29 providinga shoulder 30 which rests on the upper end of said jack piston. Theother end portion of the rod 28 is reduced, as at 3|, thus providing ashoulder 32. The reference numeral 33 designates a new bushing to beinserted which is mounted on the reduced portion 3| of the rod 28 andrests on the shoulder 32. A slidably mounted sleeve 34 on the rod 28 isadapted to be slipped over the bushing 33 for preventing expansion orbulging thereof under pressure.

When using this bushing removing and inserting arrangement, the platemember 26 is engaged with the top of the spindle assembly, for example,and the new bushing 33, which is mounted in position on the rod 28 andenclosed by the sleeve 34, is engaged with the old bushing in the lowerbearing of said spindle assembly. The jack 4 is then actuated to forcethe new bushing 33, through the medium of the rod 28,

upwardly into the bearing thus forcing the old bushing upwardly out ofsaid bearing and into the space usually provided on the spindle assemblyfor the axle. The spindle assembly may then be inverted and the bushingin the upper bearing thereof may be removed and replaced in a similarmanner. Should it be desired to simply remove the bushing withoutinserting a new one, this may be done by inserting the reduced endportion 3| of the rod 28 in the bushing and engaging the shoulder 32with one end of said bushing. Also, both bushings in the spindleassembly may be removed in this manner. The plate member 26 has formedtherein an opening 35 in which the rod 28 may be mounted when performingcertain work.

In Fig. 14 of the drawings, the reference numeral 36 designates a rodwhich is particularly adapted for removing spring shackle bolts. The rod36 comprises an end portion 31 which is engageable in the tubular jackpiston 5, together with a flange 38 which is adapted to rest on theupper end of said jack piston. In the other end portion of the rod 36 isa threaded socket 39 having a smooth counterbored or enlarged outer endportion 40. The rod 36 is adapted to be screwed on one of the usualprojecting threaded end portions of the spring shackle bolt for forcingsame out under pressure from the jack 4. Of

course, a suitable member substantially similar to those shown in Figs.5, 6, 7 and 10 but adapted for this particular operation is provided foranchoring the arms 6. Also, a new shackle bolt may be threaded into thesocket 39 and pressed into position. Still further, the rod 36 may beengaged directly at one end with a shackle bearing for removing same.

Shoulders 4| are provided on the free end portions of the arms 6adjacent the hooks l on which the plate 26 is engageable for preventingsaid arms 6 from being inserted too far through the slots 21 when thetool is being prepared for the removal of king pin bushings. This isshown to advantage in Figs. 3 and 9 of the drawings.

It is believed that the many advantages of a tool constructed inaccordance with the present invention will be readily understood andalthough preferred embodiments are as illustrated and described, it isto be understood that further modifications and changes in the detailsof construction may be resorted to which will fall within the scope ofthe invention as claimed.

What is claimed is:

A tool of the class described comprising a base having a plurality ofelongated slots therein, some of the slots being parallel to other ofthe slots and one slot extending at right angles to the other slots,adjustable legs threadedly mounted in said base, arms of a width toextend through the slots, cross pins on said arms engaged beneath thebase for securing the arms thereto for swinging and sliding movement, amember adapted for engagement with the work, hooks on the other ends ofthe arms engageable with said member, the hook portion of each arm beingof reduced thickness to form shoulders at the junction of the reducedpart with the rest of the arm, below the hooks, said shoulders formingseats for the work engaging member, a jack mounted on the base andincluding a tubular piston, and a rod removably mounted in said pistonand operatively engageable with the work.
